Description
Technical field
The present invention relates to gemstone improvement technical field more particularly to a kind of color of gemstones optimization methods.
Background technology
Jewel is liked by people always due to its special glamour, with the development of science and technology the day of people's living standard
Benefit improves, and people are increasing to the demand of jewel.Since the resource of nature is limited, the development speed in the new mineral deposit of jewel is remote
Far below the demand of society, perfect natural output grade is few.Due to the limitation of natural resources, make supply and demand that lance occur
Shield determines that people have to improve the natural gemstone of those poor qualities, to meet need of the society to natural gemstone
It asks.Therefore, gemstone improvement processing has very important meaning.
The optimized treatment method of color of gemstones is varied, and existing common color of gemstones optimization method mainly has at dyeing
Reason, heat treatment, DIFFUSION TREATMENT, radiation treatment, drift processing, coating treatment, filling treatment and split processing etc..Wherein, it dyes
Processing method is most commonly seen in jewelry industry, and almost all of gem and jade can be handled with dyeing, but dye processing
Jewel, since some dyestuffs contain harmful chemical element, wearing process may damage human body.Common
Coating treatment is to coat one layer of dyestuff in gemstone surface or cover one layer of plated film, and most of the plated film is metal film, such as CN
A kind of zirconium gemstone cutting disclosed in 105671490 A, i.e., in zirconium gem body surface evaporation metal coating;CN 1572541
The disclosed methods for manufacturing gadget of A coat one layer of overlay film containing metallic element in gemstone surface.But existing jewel
Processing method mainly has the disadvantage that:
(1) color effects that jewel after processing shows are unstable, and colour generation is poor, hence it is evident that are artificial, market
It is worth not high enough;
(2) after cameo incrustation, jewellery also have a procedure be plating, and metal film during plating due to containing gold
Phenomena such as belonging to, be easy partial exfoliation, scaling occur or play spot (referring to attached drawing 1), influences beautiful, market acceptance level and pin
Amount, be easy to cause customer complaint, does over again, increases production cost.
Therefore, how to seek it is a kind of more simple, and can get more excellent color effects color of gemstones optimization method be need
It solves the problems, such as.
